SPECIFICATION forming part of Letters Patent No. 709,760, dated September 23, 1902.

Application filed November 26, 1901. Serial No. 83,743. (No model.)

To all whom it may concern.-

Be it known that we, SAMUEL J. ELLIS and CHRISTEN NEILSEN, citizens of the United States, residing at Memphis, in the county of Shelby, State of Tennessee, have invented certain new and useful Improvements in Seed- Oake Trimmers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a seed-cake trimmer, and particularly to the construction of the cutter-head and adjacent parts.

An object of the invention is to trim the soft edges from cotton-seed oil-cakes and iinely grind the particles in the trimming action, so that they shall be in condition for again pressing without further grinding and the cake left in the best possible condition.

A further object of the invention is to provide a cutteuhead adapted in its action to hold the cake upon a table and remove the edge therefrom by a grinding action which finely divides the particles removed from the cake.

Another object of the invention is to provide an improved construction of guard and dust-collector coperating with a conveyingcarrier for removing the trimmings caught by the collector.

Other and further objects of the invention will be hereinafter set forth, and the novel features thereofdeined by the appended claims.

In the drawings, Figure l is a side elevation of the invention with the dustcollector in section. Fig. 2 is a front view thereof; Fig. 3, an elevation of the disk secured to the driving-shaft- Fig. 4. is a plan of the cutter-head, and Fig. 5 is a side elevation thereof with parts in section.

Like letters of reference refer to like parts throughout the several figures of the drawings.

The letter A'designates a vertical shaft supported in a series of bearings A', extending from any fixed support-forinstance, from a standard or beam tz-and provided at its upper end with a driving-pulley, to which power may be communicated from any suitable source. The lower end of the vertical shaft A is provided with a cutter-head B, disposed opposite the edge of a table or support Al and slightly overlapping said edge, so as to contact with a cake carried by said table. Any suitable means may be employed for supporting and moving the cake upon the table.

The cutter-head B is composed of an annular metallic ring B', having upon its outer periphery a series of teeth B2, disposed transversely, extending from the upper portion of the head downwardly. Ordinarily these teeth would cut or grind away the edge of the cake, leaving comparatively large particles of material.. For the purpose of finely dividing or practically pulverizing the material a series of grooves B3 are extended spirally upon the periphery of the cutter-head and through said teeth at substantially a right angle tothe angle of the teeth, by which a number of independent cutting surfaces or edges `are provided, so that the material removed from the cake is very finely divided andin proper condition to be again pressed. The teeth B2 are not parallel with the axis of the cutter, but are inclined diagonally to said axis, so that the pitch of the forward angle holds the cake with a slight pressure against the table A4 in the contact of the cutter therewith, thus preventing the jarring and breaking during the cut-ting operation. The cutter-head may be secured to the shaft A in anjT desired inanner-for instance, by means of a disk C, having beveled edges O', adapted to frictionally engage a similar beveled face B4 upon the inner periphery of the cutter, as shown in Fig. 5. This disk is secured to the shaft A and adapted to bear against a collar C2, While the cutterhead may be forced thereon and secured in position by a plate O3, provided with any desired secu ring means-for instance, by clamping the parts together.

Surrounding the cutter-head a guard and dust-collector D is provided and has an opening D at its front through which the cutter proj ects. This guard is pro vided at its lower portion with an inclined wall discharging into a receptacle D2, adapted to receive the collected trimmings, which may be removed therefrom by any desired means-for instance, an elevator-boot E, having a rollerbearing E within the collector and provided with buckets E2 for removing the material to any suitable point of delivery.

In the operation of the invention it will be IOO seen that the rigid vertical shaft carrying the cutter-head constructed as described will remove from the edge of the cake next the cutter the desired trimmings, which are very finely divided or ground, so as to be capable of re-pressing without any further grinding action. The material thus trimmed from the cake is carried downward by the inclination of the teeth B2, which also tend to retain the cake upon the table, and by the inclined wall of the collector carried to the portion D2 and there removed by a conveyer or any desired means. By this construction of parts the usual necessity for the further grinding of material is avoided and the trimmings at once collected and retained, so as to insure a saving in the labor involved in the trimming operation, which results are attained by the very simple and efiicient construction of parts.

It is obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described the invention and set forth its merits, what is claimed isl. ln a seed-cake trimmer, a support, a vertically-disposed drivingshaft at one side thereof, and a cutter-head thereon provided with teeth disposed diagonally to the plane of the support; substantially as specified.

2. In a seed-cake trimmer, a su pport, a vertically-disposed driving-shaft at one side thereof, a cutter-head thereon provided with teeth disposed diagonally to the plane of the support, and a series of grooves extending laterally of said teeth and through the same; substantially as specified.

3 In a seed-cake trimmer, a support, a vertically disposed driving shaft at one side thereof, a cutter-head thereon at one side of said support and provided with teeth disposed diagonally to the plane of the support, and a series of grooves extending laterally of said teeth and through the same at substantially a right angle to theinclination thereof; substantially as specified.

4. In a seed-cake trimmer, a support or table, a vertical driving-shaft at one side thereof, a toothed cutter-head carried by said shaft, and provided with teeth disposed diagonally to the plane of said support, a guard having an opening next said support and surrounding said head, an inclined dischargingwall to said guard beneath the head, an open collecting-receptacle to receive from the lower end of said wall, and a conveyer adapted to remove material from said collecting-receptacle and havinga roller-bearing therein; substantially as specified.

In testimony whereof We a'x our signatures in presence-of two witnesses.
